Investigation of the Microstructure and Distribution of Solute During Solidification of Al-Cu Alloy
(Springer Science and Business Media LLC, 1999)
Phenomenon of solidification process plays an important role in various areas like: crystal growth, casting processes, liquid phase sintering etc. Results presented in this paper contribute to investigation of the influence ...
The Influence of Sintering Conditions on the Microstructure and Magnetic Properties of Sintered SmCo5 Magnets
(Springer Science and Business Media LLC, 1999)
Since the magnetic features of the magnet of Sm-Co type are in direct connection with microstructure, it is indispensable to achieve, in the procedure of synthesis of these materials, the microstructure which ensures the ...
Dependance of avalanche photodiode characteristics on active area geometry
(Institute of Electrical and Electronics Engineers (IEEE), 1995)
The work presents an analysis of avalanche photodiode (APD) with spherical p-n junction. The calculation results are given for the dependence of the avalanche multiplication and noise parameters on geometry and on the ...
Model of Drawing Thin Glass Sheet From A Rectangular Preform and Its Applications
(Springer Science and Business Media LLC, 1999)
Glass sheets of uniform thickness, thinner than lmm, are commonly used, for example, in microelectronics, as small parts of electronic devices, and components in light microscopes, etc. Drawing glass from rectangular ...
Integrated multicolor detector utilizing 1-D photonic bandgap filter with wedge-shaped defect
(Society of Photo-Optical Instrumentation Engineers (SPIE), 1999)
Abstract
We propose a single-chip multicolor photodetector for (3-5) μm range based on a linear IR semiconductor detector array with an integrated 1-D photonic bandgap (PBG) filter. A wedge-shaped defect slab (corresponding ...
Spektrofotometrijsko određivanje acetaldehida u biološkom materijalu
(Belgrade : Serbian Chemical Society, 1994)
Za analizu korišćeni su uzorci venske krvi pripremljenih sa dodatkom ACĐ rastvora i hloralhidrata i do upotrebe čuvani na <4°C. Standardni rastvori acetaldehida su pripremljeni razblaživanjem standardnog rastvora acetaldehida ...
Dismutacija azot oksida (NO) kompleksima gvožđa i aminokiselina
(Belgrade : Serbian Chemical Society, 1999)
Reakcije NO sa prelaznim metalima čine osnovu za dejsvo NO u biološkim sistemima.
Reakcije NO sa proteinima koji sadrže hem intenzivno su izučavane. Medjutim, reakcije NO sa drugim metalnim centrima koji se nalaze u ...
Ligand field regulation of manganese redox potential in MnSODs
(Association of Greek Chemists, 1999)
Ligand field analysis (in the AOM formalism) of Mn(ll, lll) in seven Mn SOD structures reported in the Brookhaven PDB show non-negligible differences in d-orbital energies. The results are equally affected by the azimuthal ...
Antioxidant system in human erythrocytes involved in radioprotection
(The Israel Society for Biochemistry and Molecular Biology, 1991)
The aim of this work was the investigation of the influence of ionizing radiation on the erythrocyte antioxidant system and metabolism. The erythrocyte antioxidative enzymes, GSH/GSSG ratio, as well as selenium concentrations ...
Anti-oxidative enzymes in pulmonary emphysemia
(Bulgaria : Balkan Federation of Clinical Laboratory, 1996)
ln study anti-oxidative enzymes (Cat, G-Px, G-red, G-6PD11 and GSH) in patients with pulmonary emphysema, we analyzed the blood samples taken from 20 patients with global respiratory failure (10 males, mean age 56+-7.5 ...
